Ventricular septal defect (VSD) is a rare complication of transcatheter aortic valve implantation (TAVI) via the transfemoral approach. Aetiological factors leading to VSD have been reported as post-balloon dilatation, oversized prosthesis implantation, and severe calcification of the aorta. However, we present a case of VSD occurring after TAVI with an Edwards Sapien XT prosthesis without any distinct aetiological factors. We used a new technique for closure of the significant VSD; opening the left ventricular disc of the closure device in the ascending aorta and successfully implanting the device without any damage to the bioprosthetic valve.
室间隔缺损（VSD）是经股动脉途径进行经导管主动脉瓣植入术（TAVI）的一种罕见并发症。导致VSD的病因学因素已被报道为球囊扩张后、过大尺寸的假体植入以及主动脉严重钙化。然而，我们报告了一例在使用爱德华兹Sapien XT假体进行TAVI术后发生VSD的病例，且没有任何明显的病因学因素。我们采用了一种新技术来闭合较大的VSD；在升主动脉中打开闭合装置的左心室盘，并成功植入该装置，而未对生物瓣膜造成任何损伤。
